Machine for treating steaming, dyeing, finishing, washing, etc., at least one revolving ribbon

ABSTRACT

During the treatment of the travelling ribbons the guide rollers become dirtied, in particular during dyeing operations, making it necessary to clean the guide rollers, for example during a dye changeover.  
     So that the machine may continue to be used without first cleaning the guide rollers, e.g. during a dye changeover, it is proposed to arrange the guide rollers so as to be axially displaceable in the treatment compartment or to make the treatment compartment axially displaceable in relation to the guide rollers or provide an axially displaceable ribbon guide system in the treatment compartment.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to a machine for treating, steaming,dyeing, finishing, washing, etc., at least one revolving ribbon,preferably a textile ribbon, comprising a treatment compartment in whichat least two guide rollers spaced apart from one another are arrangedfor rotation, and over which the ribbon is revolved.

[0003] 2. Description of the Prior Art

[0004] These guide rollers become dirtied by the revolving ribbonsduring treatment. In particular when dyeing ribbons, it is necessary toclean the guide rollers prior to a dye changeover.

[0005] This cleaning of the guide rollers is very time-consuming andalso very expensive because the production process is stopped duringcleaning.

[0006] Accordingly it is the object of this invention to propose amachine of the type mentioned in the introduction that enables, say, adye change to take place in the shortest possible time without the needfor cleaning beforehand.

SUMMARY OF THE INVENTION

[0007] This object is achieved by arranging the guide rollers so thatthey can be displaced in the axial direction and locked in the treatmentcompartment.

[0008] The fact that they are displaceable and lockable enables theguide rollers to be moved far enough for the ribbon that is beingtreated to run over a clean section of the guide rollers.

[0009] Advantageously the guide rollers are adapted to be pushed out ofthe treatment compartment.

[0010] In the case of one practical machine for treating, steaming,dyeing, finishing, washing, etc., at least one revolving ribbon,preferably a textile ribbon, comprising a treatment compartment in whichat least two guide rollers spaced apart from one another are arrangedfor rotation, and over which the ribbon is revolved, it is an advantagefor the treatment compartment to be displaceable and lockable relativeto the guide rollers in the axial direction of said guide rollers.

[0011] In the case of another embodiment of a machine for treating,steaming, dyeing, finishing, washing, etc., at least one revolvingribbon, preferably a textile ribbon, comprising a treatment compartmentin which at least two guide rollers spaced apart from one another arearranged for rotation, and over which the ribbon is revolved, at leastone ribbon guide system is arranged in the treatment compartment so asto be displaceable and lockable in the axial direction of the guiderollers.

[0012] A controllable, dual-action pressure cylinder is preferablyprovided for the displacement.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The invention is illustrated by way of examples in the drawings,wherein:

[0014]FIGS. 1 and 2 show a machine with displaceable guide rollers;

[0015]FIGS. 3 and 4 show a machine with a displaceable treatmentcompartment; and

[0016]FIGS. 5 and 6 show a machine with a displaceable ribbon guidesystem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017]FIGS. 1 and 2 depict guide rollers 2 arranged spaced apart fromone another at the top and bottom of a treatment compartment 1. A ribbon3 intended for treatment is revolved over the guide rollers 2, which areeither free-running or are driven.

[0018] As FIGS. 1 and 2 show, the guide rollers 2 rest on shafts 4 whichare held in a bracket 5 on the treatment compartment 1.

[0019] With the help of dual-action pressure cylinders 6 whoseconnecting rods 7 are joined to the guide rollers 2, the guide rollerscan be pushed out of the position represented in FIG. 1, in thedirection identified by the arrows 8, and into the position representedin FIG. 2, with the result that the ribbon runs over clean sections ofthe guide rollers 2. As FIG. 2 shows, the guide rollers 2 may be movedback in the arrowed direction 9 into the position represented in FIG. 1.

[0020] Because sections of the guide rollers 2 are in each case situatedoutside the treatment compartment 2, these sections can be cleanedduring the production process, which means that by suitably displacingthe guide rollers 2 there are always clean sections of the guide rollersavailable.

[0021] In the embodiment of the machine according to the invention asseen in FIGS. 3 and 4, the treatment compartment 1 is displaceablyarranged on the brackets 5, in which the guide rollers 2 are mounted forrotation on the shafts 4.

[0022] The connecting rods 7 of the pressure cylinders 6 are joined tothe brackets 5, thereby enabling the treatment compartment 1 to bepushed out of the position represented in FIG. 3, in the arroweddirection 10 and into the position represented in FIG. 4, where it canbe locked in place. The treatment compartment 1 can be moved, in thearrowed direction 11, out of the position represented in FIG. 4 and backinto the position represented in FIG. 3.

[0023] Likewise in the case of this embodiment those sections of theguide rollers 2 that lie outside the treatment compartment 1 can becleaned during operation, with the result that there are always cleansections of the guide rollers available.

[0024] In the case of the embodiment of a machine according to theinvention as depicted in FIGS. 5 and 6, a ribbon guide system 12 isarranged in the treatment compartment 1 so as to move to and fro in thearrowed direction 13 into the positions represented in FIGS. 5 and 6, inthe axial direction of the guide rollers 2. The ribbon guide system 12is in each case displaced by an amount corresponding to the distancebetween the revolving ribbon 3. If longer guide rollers 2 are provided,displacement of the ribbon guide system 12 can also take place across abigger range.

[0025] Likewise in the case of the embodiments seen in FIGS. 1 to 4there may be provision for displaceability by one ribbon's width in eachcase, thereby making possible displacement in several steps in order forclean sections of the guide rollers 2 to always be available.

[0026] The embodiment of the machine seen in FIGS. 5 and 6 hasparticular applications with closed treatment compartments 1 in whichhot air or hot steam or other media are used for treating the ribbons 3.
